Answer:

For question 18, the answer is 55 degrees.

19. 115 degrees.

Step-by-step explanation:

18) Complementary angles have a sum of 90 degrees, so 35 plus 55 equals 90.

19) Since angle 8 and angle 5 have the same measure, the measure of angle 5 is 115 degrees.

I hope this helped! :-)

Which of the graphs below correctly solves for x in the equation −x2 − 3x − 1 = −x − 4?

Tanzania [10]

We have
−x²<span> − 3x − 1 = −x − 4

let
f(x)=</span>−x² − 3x − 1
g(x)= −x − 4
the solution for
f(x)=g(x) is the intersection both graphs

using a graph tool
see the attached figure

the solution are the points
(-3,-1)
and
(1,-5)
